Objective To develop a quality of life scale for patients with congenital external and middle ear malformation, and to explore its reliability and validity. Methods The initial quality of life scale for patients with congenital external and middle ear malformation was constructed based on quality of life scales from home and abroad. A total of 140 patients with congenital external and middle ear malformation had been recruited in the study. After pretest and item sifting, the quality of life scale was constructed, and its reliability and validity were evaluated. Results Eighteen-item quality of life scale for patients with congenital external and middle ear malformation was constructed, which included three parts: physiological function, psychological status and social interaction. The retest reliability was 0. 878; split-half reliability coefficient and Cronbach's alpha coefficient were 0.927 and 0. 899, respectively. The results of factor analysis showed satisfactory construct validity. The reliability and validity of this scale was consistent with the demands of psychometrics. Conclusion Congenital external and middle ear malformation quality of life scale is believable and effective, which can be used for clinical practice.%目的 编制一个评价先天性外中耳畸形患者生活质量的多维测评量表,并对该量表进行信度和效度分析.方法 参考国内外生活质量量表,构成患者生活质量初始量表,对140例先天性外中耳畸形患者进行生活质量的预测试后,进行条目筛选,建立量表,并对量表作信度和效度检验.结果 编制的先天性外中耳畸形患者生活质量量表(简称量表)包含生理功能、心理状态、社会关系等三个维度,18项条目.量表的重测信度为0.878,分半信度为0.927,克朗巴赫α系数为0.899;经因子分析获得的因子结构与量表设计的预想结构一致,具有较好的结构效度.量表的信度和效度符合心理测量学要求.结论 本研究量表是可信、有效和敏感的,可应用于临床评估.
